Letters Patent No. 97,507, dated Bccember 7, 1869.

'IMPROVED TUYERE.

'ne Schedule referred to xn these Letters Patent and making part ofthe name To all whom fit may concern Be it known that I, J. F. EARLY, of Kipton St tion, in the county of Lorain, and State of Ohio, have invented certain new and useful Improvements in Tuyere-Irons; and I do hereby declare that the following is a full and complete description of the same, reference being had `to the accompanying drawings, making part of this specification..

Objective. This invention relates to a tuyere-iron for smiths forges, the construction of which being such that the tnyere is'surrounded with a current otwater, whereby it is'prevented from rapidly burning out; the same .view of which is shown in tig. 2.

Said body consists of a water-tight annular chamber, B, iig. 4, the inner walls O forming a passage-way p `or throat, D, in which is fitted a concave valve, E, at-

tached to the upper end of the `stem F.

The lower end of said stem is provided with a ratchet, c, in which a pinion-wheel, Gr, is made 'to engage, and whereby the valve is raised or lowered for closing and opening the throat.

The valve, as will be seen, is made to fit 'closely therein' 'at the top, so that on beingforced upward by the pinion, it will shut the throat tightly,""as and for apurpose hereinafter shown.

II are water-tubesl or pipes, wherebywater is conveyed into the chamber B.

To the under side of the body is attached an ashbox, I communicating directly with the passage-way.`

J is an air or blast-pipe, connected with that from the blower.

The practical operation of this tuyere is as follows:

It is built into the forge, in the position shown in iig. 2, so that thepipes H and J will penetrate the back of the lire-place. The tuyere thus forms the bed on which the fire is made, and which, being concave, it holds a portion of the fuel within and upon the valve.

rlhe chamber B is lled'with water by connecting the pipe H to the reservoir, which, being placed at a convenient height,'will afford-a constant supply thereto. The pipe J, on being connected with that of the blower, the blast is fed to'the fire byopening the valve, which is readily done by means of the hand-wheel K, whereby is operated the ratchet;pinion, the air passing into the ash-box immediately below the chamber,

thence through the passage-way, around the sides of the valve, to the bottom of thelire.

As the valve does not fitclosely in the passageway only at the throat or top thereof, it Awill be obvious vthat the volume of air allowed to pass through is easily regulated by the valve, by keepingit 1nore`o`r less open,

as the condition of the fire may require.

By keeping the chamber constantly filled with Water, it will be obvious that the tuyere cannot soon burn out, thereby saving the expense of a new tuyere, which, if used without the presence of water, requires to be renewed quite often. n

The dirt and ashesthat may fall through the valve down into the ash-box, are removed therefrom by withdrawing the slide L, which will allow the ashes to fall out through the-bottom to the ash-pit.v

That I claim as my improvement, and desire to secure by Letters Patent, is-

The herein-described tuyerc, consisting ot' the waterchainber B, ash-box I, valve E, ratchet and pinion a.

and G, and pipes H and J, all .constructed and ar ranged to operate as and for the purpose set forth.
